Oort cloud or Kuiper belt, long elliptical orbit

Detailed explanation-1: -Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.
Detailed explanation-2: -The Kuiper belt is a disk-shaped region of space beyond the orbit of Neptune that is dynamically stable. It is the source of short-period comets. The Oort cloud is much farther out than the Kuiper belt. It is a spherical region surrounding the Sun out to near 50, 000 AU.
Detailed explanation-3: -Long-period comets (which take more than 200 years to orbit the Sun) probably come from the Oort Cloud, which is sometimes described as a “cometary reservoir."
Detailed explanation-4: -The short-period comets are thought to originate in the Kuiper Belt, an area outside Neptune’s orbit (from about 30 to 50 AU) that has many icy comet-like objects. The long-period comets tend to have orbits that are randomly oriented, and not necessarily anywhere near the ecliptic.
